Heated yagi antenna
WebThe Yagi-Uda antenna or Yagi Antenna is one of the most brilliant antenna designs. It is simple to construct and has a high gain, typically greater than 10 dB. The Yagi-Uda antennas typically operate in the HF to UHF bands (about 3 MHz to 3 GHz), although their bandwidth is typically small, on the order of a few percent of the center frequency. WebIn this paper, the design and analysis of a 2.4 GHz Yagi-Uda type antenna has been presented. The antenna is modelled and analyzed using the Ansys HFSS electromagnetic simulation software. Cardboard with a dielectric constant of 1.78 is used to fix the antenna elements on the same plane such as the director and the reflector. The designed and …
